He could feel the weight of the load behind him shifting. The cab of his truck, rolling.

Thank God, he says, there were no vehicles next to him as the semi toppled over.

"Yeah, I'm just glad nobody got hurt," said Hall.

The crash shut down the entrance ramp, as work crews removed the debris and eventually up righted the truck.

The big rig belongs to International Core Supply in Ybor City.

The wreck itself had no effect on I-275, but traffic along Bearss Avenue was stacked solid in both directions.

As impatience grew, one woman said it almost created more problems.

"I mean back there, was almost another accident getting through the intersection," she said.

Hall says he's been driving professionally since 1996 and that nothing like this had ever happened to him before. Investigators said their first priorities were to get the ramp cleared in time for rush hour, which it was, and then answer some key questions.

"We've gotta determine how fast he was going, the load, the weight... a few things to look at," said FHP trooper Jeremy Chohen.

In addition to the Florida Highway patrol, a state transportation inspector was on hand. The semi, they say, may have just been weighed minutes before the crash.

They intended to look at that report as well as any other potential problems with the truck itself.

Hall suffered a cut to the back of his head, but no major injuries and no other people were hurt.

Earlier Story:

Tampa, Florida -- It's not as bad as it looks, honest.

A tractor trailer hauling about 15 crushed cars flipped on its side Wednesday afternoon, spilling the vehicles over the roadway.

The Florida Highway Patrol says the accident happened at the southbound entrance ramp to Interstate 275 at Bearss Avenue. It's not clear what led to the crash.

Crews are now working to clear the roadway of the truck and all the crushed vehicles.

Delays of 15-20 minutes in the area can be expected. The FHP isn't sure if they'll be able to clear the scene by 5 p.m.
